[0002] At present, galvanized steel pipes are usually hot-dip galvanized steel pipes. Galvanized steel pipes are welded steel pipes with a hot-dip galvanized or electro-galvanized layer on the surface. Galvanization can increase the corrosion resistance of the steel pipe and extend its service life.

[0003] Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are widely used in manufacturing industries such as construction, machinery, coal mines, chemical industries, electric power, railway vehicles, the automotive industry, highways, bridges, containers, sports facilities, agricultural machinery, and greenhouse construction. They are also used as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields, oil heaters, condensation coolers, and pipes for coal distillation wash oil exchangers in chemical coking equipment, as well as pipe piles for trestles and support pipes for mine tunnels.

[0004] During the processing of galvanized pipes, in order to adapt to different installation and use occasions, corresponding bending operations are required. Traditional bending is manually operated using bending equipment, resulting in low work efficiency. With the upgrade of bending equipment, hydraulic bending equipment has been used in the bending operation of galvanized pipes. Currently, only one galvanized pipe can be bent at a time using hydraulic bending equipment. Although it is labor-saving and time-saving, the corresponding efficiency is still not high.
